Volcanic Pottery Vase

This outstanding studio vase has one of the best uses of volcanic glaze I have seen. It measures 15" tall and unfortunately is unsigned. There are 2 significant areas on the lip of the vase where the thick glaze appears to have bubbled and chaffed off. These measure 1/4" and 5/8" in length. There is also a small fleabite chip to the side of the lip.
